- Timing of backup. Whilst backups are being taken this process can interfere with users’ ability to retrieve information. This is why backups are generally made outside of working hours to minimise the impact upon other people using the computer system.
- Performance. Taking a backup can also have an effect on the performance of the computer system or network because it has to complete a number of different tasks at the same time. This can sometime cause users systems to slow down.
- Not understanding that backup requires a process and set of procedures that need to be adhered to, i.e. who should take the backup, when should it be completed, where it should be kept and what recovery plans are in place if data is lost, etc.
- Costs. Pricing of storage needs to be factored in when making a decision as it is important to have the right amount of storage as well as the most effective type of storage for your organisation.
- Manpower costs. Whether you are an individual or a large organisation, there can be considerable effort required to take and retain regular backups.
- Data must be protected from unauthorised access. This is particular important when it comes to personnel records as there may be an implication from the Data Protection Act.
- Keeping the backup either near the current system or in an unsafe place, i.e. if there were to be a fire or flood and the backup is destroyed, then the system would be rendered pointless.
- While having a backup is important, without a recovery plan or an effective method of ensuring that the information can be reloaded or accessed, then the system is useless.
